HARRY BROUSSEAU AND GILBERT PATTERSON, OF NEWBERRY, MICHIGAN.
UNITED STATES PATENT OFFICE.
ROTARY VALVE.
SPECIFICATION forming part of Letters-Patent No. 465,917, dated December 29, 1891.
Application filed July 27, 1891. Serial No. 400,884. (No model.)
To aZZ whom it may concern:
Be it known that we, HARRY BROUSSEAU and GILBERT PATTERSON, citizens of the United States, residing at Newberry, in the county of Luce and State of Michigan, have invented certain new and useful Improvements in R0- tary Valves; and we do declare the following to be afull, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the figures of reference marked thereon, which form a part of this specification.
Our invention relates to rotary valves, its object being to provide a valve that will always wear to the seat and be balanced and easily adjusted.
Figure 1 is a top View of the valve and steamchest. Fig. 2 shows the adj Listing-screw and wedge; Fig. 3, outside view of steam-chest and crank; Fig. 4, sectional View of valve and steam-chest; Fig. 5, sectional viewof frictionrollers.
1 isthe valve-post, having the case-harden ed steel shoe 5' resting on case-hardened friction-rollers 11 in the foot-bearing 4.
2 2 is the live-steam port, and 3 3 the exhaust-port.
14. is the exhaust-cavity on one side of the valve-post; 13, the counter-balance; 18, the counterbalance-seat; 17, the valve-seat, and 16 the steam-chest.
15 is the upper journal with stuffing-box 12 and valve-spindle 10, onto which is connected the rock-arm 8.
9 is a bracket steadying the spindle 10.
19 19 is the inside of the steam-chest, and 21 the live-steam port.
6 is an adj Listing-wedge. Its shape is shown in Fig. 2, with the adjusting-screw 22 and connections viz., screw-holder 23, inside steam-chest, and stuffing-box 20. It is evident that by turning this screw the wedge may be forced in or out, thus adjusting the seat, and by loosening the crank-arm the valve may be adjusted without opening the chest.
Fig. 4 shows the construction of the valveseat 17, and counterbalance-seat 18, being of joint, and there being steam equally'at the top and bottom of the valve-post there is little or no weight on the rollers. By having two exhaust-ports the cavities can be made smaller, thus throwing less weight on the 0pposite side as the engine exhausts.
\Ve do not wish to confine ourselves to any special form of construction, and therefore any change that comes withinordinary mechanical skill may be made without departing from the principle of our invention.
\Vhat we claim as new, and desire to secure by Letters Patent, is-
1. A rotary balanced valve consisting of the valve-post 1, resting upon friction-rollers 11, the friction-rollers 11, the exhaust-cavities 14 14, the counter-balance 13, the steamports 2 2, the exhaust 3 3, valve-seat 17, and counterbalance-seat 18, built on an incline to each other from the top, substantially as specified.
2. An adj Listing-wedge for rotary balanced valves having its upper face straight, its lower surface tapering from the head to the point, adapted to be inserted under the foot-bearing of the valve-post, and provided with the screw-bolt 22, screw-holder 23, and stuffingbox 20 for adjusting the wedge from the outside, substantially as described. 7
3. A rotary balanced valve consisting of I the valve-post 1, the shoe 5, the friction-rollers 11, the foot-bearing 4:, the exhaust-cavities 14 14:, the steam-ports 2 2, exhaust 3 3, and valve-seat 17 and counterbalance-seat 18, built on an incline to each other from the top and provided with the adjustingwedge 6 and screw-bolt 22, substantially as specified. 1
4. A rotary balanced valve provided with friction-rollers 11 under the valve-post, made cone shape, the apex of the cone being toward the center, thereby preventing. the bearing wearing to a tight joint, substantially as described.
5. A rotary balanced valve consisting of the journal 15, valve-spindle l0, and rock-arm [o the valve-post 1, having the foot-shoe 5, the 8, substantially as specified.
